The answer should be x=60. ABD are an equilateral triangle all the angles must add up to 180. 60*3=180. Also if you have a protractor you can measure the angle C, the 60 degrees part and measure it against A, D and B. Hope this helps.

Answer:

x<5

Open circle at 5 going to the left

x >1

Open circle at 1 going to the right

Step-by-step explanation:

7x -19 < 16

Add 19 to each side

7x -19 +19< 16+19

7x< 35

Divide by 7

7x/7 < 35/7

x<5

Open circle at 5 going to the left

9+3x>12

Subtract 9 from each side

9-9 +3x >12-9

3x >3

3x/3 >3/3

x >1

Open circle at 1 going to the right

HELP PLZ!

Elza [17]

Answer:

$-5 = y$

Step-by-step explanation:

{y = 6x − 11

{y = x² + 4x − 10

x² + 4x − 10 = 6x − 11

- [6x − 11] - [6x − 11]

________________________

x² - 2x + 1

${[x - 1]}^{2} = 0$

1 = x [Plug this back into both equations above to get the y-coordinate of −5]; −5 = y

I am joyous to assist you anytime.
